Vesic's solutions to cavity expansion that include cylindrical cavity expansion and spherical cavity expansion are introduced. Then cylindrical cavity expansion theory is applied to study compaction effect of pile driving in saturated soil. Based on the results of conventional triaxial tests, a trilinear curve model is used to simulate stress-strain curve of strain-softening materials. Meanwhile, trilinear curves are also used to simulate curves of volumetric strain, minor principal strain and major principal strain. By using elasto-plastic theory, analytical solutions to cylindrical cavity expansion in strain-softening soil are presented. According to the mechanism of statically pressed pile driving, compaction effect of pile tip can be viewed as hemispheric cavity expansion. Therefore spherical cavity expansion theory is applied to obtain the solutions to stress, strain, displacement fields and final pressure. Resistance force of pile tip is calculated to estimate static pressure.

Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.

对经曲面断层片筛选出的18例19枚埋伏牙进行牙科三维CT检查，扫描层厚1.0mm，重建后进行图像三维断面显示（包括水平位，矢状位，冠状位），对牙位图像进行分析及测量（包括埋伏牙牙长轴的角度，牙根弯曲度，牙冠的最大径，与骨皮质的距离，与邻牙根、神经孔／管的距离；骨质的厚度、高度等）。

The accuracy aspect in three-dimensional measuring procedure, westudy the length of Cun, Guan and Chi on TCM pulse diagnosis firstly. The result showed that the the mean value of relative bias of DWP compared with EL×6% was close to 0%.(males = 2.1%±12.2%, females=0.2%±12.6%). Therefore, by using "the highest point of PB" as the lower limit of Cun and palpating down proximally, the position of Guan and Chi can be found.
